A VPN (virtual private network) is a service that sends your internet traffic through an encrypted connection to a server run by the VPN provider. It's useful in some situations and oversold in others. Here's an honest look.

1. What a VPN actually does

It encrypts the traffic between your device and the VPN provider's server, and websites see the provider's server address instead of yours. That's it. Your traffic still goes out to the internet from that server, and the provider can see it in the same way your internet provider otherwise would.

2. When it can help

Using public Wi-Fi at cafes, airports or hotels, where you don't control the network.
Working remotely, if your employer asks you to use one.
Keeping your browsing less visible to your own internet provider.

3. What a VPN won't do

A VPN doesn't make you anonymous. It won't stop scams, phishing emails or malware, and it doesn't stop sites you log in to from knowing who you are. Cookies, accounts and browser fingerprinting still work. You're also shifting trust from your internet provider to the VPN provider, so who runs the service matters.

4. Keep it legal

A VPN is legal to use in Australia. Using one doesn't make an illegal activity legal, and streaming services' own terms may limit how you can use them. Check the terms of any service you use.

5. Do the basics first

Strong, unique passwords, multi-factor authentication and keeping your software updated do more for most people than a VPN. Scamwatch is a good place to learn the common scams to watch for.

The short version

A VPN encrypts traffic to the provider and hides your address from sites.
It doesn't make you anonymous or stop scams.
You're trusting the VPN provider instead, so choose carefully.
Use it legally, and sort out passwords and updates first.

We don't list prices here, because they change depending on where you are. Check the provider's own site for current prices and plans.

A VPN can be a handy extra on public Wi-Fi, like at an airport or a cafe. It encrypts the connection between your device and the VPN provider, which makes it harder for others on the same network to read what you send. A VPN works best as one layer alongside strong, unique passwords, regular updates and two-factor authentication. NordVPN is one VPN provider. Nord says one account can protect up to 10 devices at once.
